WFD Cycle 2 lake littoral invertebrates classification
Description
This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Macro-invertebrates in lakes. Lake acidification macro invertebrate metric (LAMM) is a species/ abundance weighted method that assesses the degree to which anthropogenic acidification has impacted macro-invertebrate communities. Results are compared to reference conditions (ie. Non-impacted) and the index quantifies the deviation from pristine status via an Ecological Quality Ratio (EQR). Two sets of reference conditions are used for Humic & Clear waters.
Classification bands are applied from High (little or no impact) to moderate or worse (significantly impacted). Confidence of class (CoC) is also calculated. This gives the likelihood of the site belonging to any particular class for WFD reporting. Attribution statement: © Environment Agency copyright and/or database right 2015. All rights reserved.
